To all whom t 'may concern:

Be it known that l, ANDREW MORRISON, a citizen of the United States, and a resident of Pittsburgh, Allegheny county, Pennsylvania, have invented a new and useful Improvement-in Guard-Rails, of which the following is a full, clear, and exact description, reference being had to .the accompanying drawings, forming part ofthis specification,

\ in Which-- Figures l, 2, 3, 5 and 6 are sectional views showing ditt'erent forms of vmy invention;`

Fig. 4 is a plan fv'iewv of a portion of a guard rail with the guard member, in section; and

Figs. 7 and 8 are plan views showing different forms of the guard/(rail applied to a tratlio rail. i

My invention has relation to guard rails of that type in which the guard member has an integral base portion extending underneath the base ofy theadjacent main or traiiic rail; and is 'designed to provide a guard rail of this kind which can be readily rolled preferably from steel sutiiciently soft to permit it to be punched to form the necessary spike holes.

ln the preferred form of my invention, I secure to the guard member a head or wearing portion of harder metal. My invention also provides a guard rail having provision for its adjustment relatively to the main or traffic rail; and also a guard rail which is so constructed as to have a maximum of strength and efficiency in use.

ln the dra-Wings, the numeral Wherever seen, designates a main or traitic rail.

Referring tiret to the form ot my invention shown-1n Fig. l, the guard rail'consists of a base portion 3 which extends outwardly underneath the base of the traffic rail for substantially the Afull length ot' the guard rail, and which is formed with an integral upwardly projecting guard member 4. rThe base portion 3 extends continuously underneath and inside ot` the guard memberef, the extension to the inside o'l" said member being preferably carried a sutiicient distance to form a toot or brace against the leverage exerted by wheels against the upper inner ln practice it has .been #found that this leverage sets up strains in the base portions ot` the guard rails, which cause them to break between the guard member and the main rail. T his is ei'i'ectually prevented by extending the base portion oi the guard rail in the manner described. The guard rail of the section shown can be readily rolled of steel suiciently sott to permit spike holes to be' punched therein. 5 designates a wear strip or head ot' harder met-al, which is secured to the inner side ot' the upper portion ot' the guard member il, preferably by rivets (i. The head or Wear plate may be of various forms, some of which are shown in Figs. l, Q, 3 and 6. The construction shown in Fig. 2 diii'ers from that shown in Fig. 1. only in the form of this u'ear strip or head.

ln the constructionshown in Fig. 3, the guard member, instead of extending in a direct vertical direction, has its lower portion la inclined inwardly toward the traffic rail, while its upper portion is in a vertical position.

In the modification shown in Fig. 5,'l have shown the head 5 as formed integral with the upwardly extending guard member, but do not consider this construction as advantageous as those ofthe other forms olescribed, since it the guard rail is forn'ied ot metal sutiiciently hard so that the head portion ot the Q 'uard member will stand the. Wear to which it is subjected, it is too hard to be punch-ed and may break in service.

ln the construction shown in Fig. fl, the upper end oi' the upright guard member is shown as bent inwardly at 5b, at substantially right angles. in practice, l prefer to roll the guard member ot a height suticient tor the higm4 et section ot' the main or 'tratiicv 'rail which may be employed; and in using the guard rail xvitli a 'lralic rail oi' .lower section, the upper portion of this guard .member either beul'. as shofafn in Fig. (il, or is sheared ott to the proper height. in this manner the number of guard rail sec-y tions Which it is required to roll is reduced to one staud a rd torni tor all heights oi rails.

Fig. 7 shows the iforui o'f'guard rail Whichl illustrated in Fig. l, as applied to a main or trallic rail. The end portions ot the1 guard rail are bent inwardly, so that the guard member is caused to diverge at its ends iu the usual manner from the trailic rail.

Fig. 8 shows a modification in which the base portion of the guard rail instead of being solid throughout its length is partially cut away betireen the tics, as shown at 7.

Each ot' the various 'forms of guard rails 110 illustrated in provided with Spike holes 8 intermediate the ui'nvardly pro]ect1ng guard member and the inner edge of the base flange of the main rail to receive spikes 9. These holes are. preferably transversely elongated. The base portion is also provided with the staggered spike holesl l0 through any one of which may be driven spikes l1 en aging the outer edge of the base flange of the traiic rail. The elongation of the hole 8 and the staggered arrangement of the holes l0 pro- Vide for a relative adjustment of the main and guard rails.

The inward extension ot' the base inside of the guard member may or may not be secured by spikes 12.

By reason of the overhang of the wear strip or head 5, l make provision of a sntiicient space between fthe inner edge of the base iange ot' the t-railie rail and the guard member to receive the spile'holes 8 of suiiicient elongation to provide for the necessary adjustment. The extent of this space may be still further increased by inelining the lower portion of the guard member7 as shown in Fig. 3.

While I prefer in all cases to employ the inward extension of the base portion, as above desnribed, this ma -be omitted as shownin Fig. (3, and still retain the advantage of the other features of my in\ention.

al. A guard rail structure. comprising a base member ha ving an integral guard portion rising therefrom, the said member hav-- ing a flat main rail-supj'iorting portion' of.

uniform thickness extending inwardly from the base o't` the guard rail to a point beyond the outer edge of the main rail, said guard portion being set away. from the main rail sul lciently to provide clearance between the base ot' the main rail and the guard'poition for an adjustable fastening for the main rail, said fastening directly engaging the 4vertical edgel of the base of the main rail and holding itl in alinement, substantially as described.

2. A guard rail structure, comprising-abase and an integral guard member rising" from the base,` said guard member having a, relatively thin upper portion which can be either removed or bent downwardly to vary the height of the guard, member, substantially as described.

3. A guard rail struct-ure, comprising a base and an enlarged guard member rising from the base, said guard member tapering upwardly and being relatively thin at its upper portion, whereby such portion may be removed or bent over to therebyvary the height of said member, substantially as described.

t. A guard rail structure, comprising a base and an integral guard member rising from the base, said guard member tapering upwardly and being relatively thin at it-s upper portion, whereby such portion may be removed or bent over to thereby vary the height of said member, the latter having a vertical inner surface to form a seat for a wear strip, substantially asdescribed.

5. A guard rail structure, comprising an integral rolled section having a base portion and an upstanding guard portion, the latter having a rela-tively thin upper portion formed with a, flat roll-finished face, and a wear and stiifening piece secured lo said face, the bottom of ,said piece being suiii-A cient-ly high to permit a main rail fasten# ing to be driven through the base portion under said piece, substantially as described.

In testimony whereof7 I have hereunto set my hand.
